I've found out that none of Qt 5.9.2 openGL examples works properly on my old notebook - Thinkpad t60p with ATI FireGL V5250, Windows 7 64bit. Here is just a raster captured under the application main window instead of scene content. I've tried all gl-examples - from legacy to QML. Result is the same.
Contextinfo example shows that ATI driver support openGL 2.1.
Qt3 examples show openGL scenes absolutely correctly.
What may be the matter? It's a very important question for me because many of our clients still use old hardware.

What exact problem do you have ?

Do you mean Qt 5.3 ?

I use Qt 5.9.2.
The problem is that any opengl scene isn't visible where it should be. Instead scene I see a captured part of the desktop under an application window - part of Qt Creator text editor window for example.
I'm not sure but I haven't noticed this effect in early 5.x. I check 5.6 tomorrow.
